Given:
Mason misses 25% of the free throws he attempts in a season.
Number of missed free throws = 52
To find:
The total number of free throws.
Solution:
Let x be the total number of free throws.
Mason misses 25% of the free throws he attempts in a season.
Number of missed throws = 25% of x
Number of missed free throws = 52
Now,
[tex]\dfrac{25}{100}x=52[/tex]
[tex]\dfrac{1}{4}x=52[/tex]
Multiply both sides by 4.
[tex]x=52\times 4[/tex]
[tex]x=208[/tex]
Therefore, the total number of free throws is 208.
Round the following numbers to the nearest 10
a) 83
b) 127
c) 245
Answer:
a)80
b)250
c)130
Step-by-step explanation:
Answer:
a)
Step-by-step explanation:
83 = 3 is less than 5
so,83-3=80
b) l27 = 7 is more than 5
so 127 + 3 =30
c) 245 = 5 is equal to 5
so 245+5=250
the refrigerators at Hal's discount appliances are 30% off the original price during the 12th anniversary spectacular.MR Hanson is shopping for a new refrigerator and has a coupon for a 12% discount off the sale price.if the original price of a refrigerator is 1249 how much will MR.Hanson pay for the refrigerator before tax
Answer:
$769.38
Step-by-step explanation:
First, find the cost with the 30% off original price:
1249(0.7)
= 874.3
Now, find the cost with the 12% discount off sale price:
874.3(0.88)
= 769.38
So, Mr Hanson would pay $769.38 before tax
Answer:
$769.38
Step-by-step explanation:
Original price: $1249
100% - 30% = 70%
A 30% discount means that you pay 70% of the amount.
Apply a 30% discount: 0.70 * $1249 = $874.30
100% - 12% = 88%
A 12% discount means that you pay 88% of the amount.
Apply a 12% discount: 0.88 * $874.30 = $769.384
Answer: $769.38
Convert y = 5x2 + 20x + 11 to VERTEX form.
Answer:
y =5(x+2)2−6 is the correct ans
The vertex form of quadratic equation is expressed as:
y = a (x - h) + k
We manipulate the given equation to be the same as the vertex form. First we transpose the constants to the left-hand side.
y - 14 = 5x+ 20x
Then, we factor out in right hand side the coefficient of the x² term.
y- 14 = 5 (x + 4x)
We divide the coefficient of the x term with 2 and take its square. We add this value to both sides of the equation but we should remember that in the left-hand side we should multiply this value with five to keep it balanced.
y - 14 + 20 = 5 (x + 4x +4)
We simplify the right-hand side as:
y =5(x+2)2−6
(hope that helps can i plz have brainlist :D hehe)
Step-by-step explanation:
The vertex form is one of the most commonly used forms for quadratic functions, as it emphasizes the dimensions of the substring graph's vertex.
Vertex form:A vertex form of a solution is a unique way of spelling out such a parabola's equation. Usually, a quadratic equation is expressed as an x² + bx + c, which is a parabola if plotted on a graph.[tex]\to y= 5x^2+20x+11\\\\[/tex]
Solving the equation:
[tex]\to y= 5(x+2)^2-9\\\\\to y= 5 (x^2+2^2+ 2\times 2 x)-9\\\\\to y= 5 (x^2+4+ 4x)-9\\\\\to y= 5x^2+ 20+ 20x-9\\\\\to y= 5x^2+ 20x +11\\\\[/tex]
So, the value is "5(x+2)²-9".

Step-by-step explanation:
A rancher needs to build a water storage tank for her cattle. The cattle drink 3 cubic meters of water each day and the rancher wants the new tank to hold a 5-day supply of water. If the new tank has a radius of 2 meters, how tall will the tank need to be?
Answer:
The height of the storage tank would be approximately 1.2 m.
Step-by-step explanation:
The cattle drink 3 cubic meters of water each day.
For 5 days,
the cattle would drink = 3 cubic meters x 5
= 15 cubic meters of water
Thus,
The volume of the storage tank = 15 cubic meters
But,
volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h
where r is the radius and h the height.
So that,
15 = [tex]\frac{22}{7}[/tex] x [tex]2^{2}[/tex] x h
15 = [tex]\frac{22}{7}[/tex] x 4 x h
15 = 12.57h
h = [tex]\frac{15}{12.57}[/tex]
= 1.1933
h = 1.2 m
The height of the storage tank would be approximately 1.2 m.

How will the solution of the system y>2x+2/3 and y<2x1/3 change if the inequality sign on both inequalities is reversed
Answer:
We have the inequalities:
y > 2*x + 2/3
y < 2*x + 1/3
First, we need to understand how to see the solutions of each one of these.
y > 2*x + 2/3
The solution set of this inequality will be ALL the points above the line:
y = 2*x + 2/3
And the solution of the inequality:
y < 2*x + 1/3
Will be the set of all the points below the line:
y = 2*x + 1/3
Notice that line "y = 2*x + 2/3" is above than the line "y = 2*x + 1/3"
Then the system:
y > 2*x + 2/3
y < 2*x + 1/3
Has no solutions.
If we reverse both inequalities, we will get:
y < 2*x + 2/3
y > 2*x + 1/3
Now the solution of the first inequality will be all of the region below the line, and the solution for the second will be all the region above the line.
In this case, the solution of the system will be all the region between both lines, as we can see on the graph below. Where the solution of the system is the doubled shaded area.

If a =
-5i and b = -4x, then find the value of a+b in fully simplified form.
If a =-5i and b = -4x the value of a+b in the fully simplified form will be 5i-4x.
What is a complex number?It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
It is given that,a =-5i and b = -4x
We have to find the value of a+b in a fully simplified form.
We have to apply the arithmetic operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
=a+b
= -5i-4x
Thus, if a =-5i and b = -4x the value of a+b in the fully simplified form will be 5i-4x.

Answer:

Step-by-step explanation:

let x represent blueberry pie and y blackberry pie, then
x + 2y = 53 → (1)
10x + 3y = 224 → (2)
Multiplying (1) by - 10 and adding to (2) will eliminate x
- 10x - 20y = - 530 → (3)
Add (2) and (3) term by term to eliminate x
0 - 17y = - 306
- 17y = - 306 ( divide both sides by - 17 )
y = 18
Substitute y = 18 into either of the 2 equations and solve for x
Substituting into (1)
x + 2(18) = 53
x + 36 = 53 ( subtract 36 from both sides )
x = 17
Then
the cost of 1 blueberry pie is $17 and 1 blackberry pie is $18

The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
(11)
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, 2) and (x₂, y₂ ) = (0, 3)
m = [tex]\frac{3-2}{0-4}[/tex] = - [tex]\frac{1}{4}[/tex]
The line crosses the y- axis at (0, 3 ) ⇒ b = 3
y = - [tex]\frac{1}{4}[/tex] x + 3 ← equation of line
(12)
(x₁, y₁ ) = (- 3, 1) and (x₂, y₂ ) = (4, 2)
m = [tex]\frac{2-1}{4+3}[/tex] = [tex]\frac{1}{7}[/tex] , then
y = [tex]\frac{1}{7}[/tex] x + b ← is the partial equation
To find b substitute either of the 2 points into the partial equation
Using (3, 1 ), then
1 = [tex]\frac{3}{7}[/tex] + b ⇒ b = 1 - [tex]\frac{3}{7}[/tex] = [tex]\frac{4}{7}[/tex]
y = [tex]\frac{1}{7}[/tex] x + [tex]\frac{4}{7}[/tex] ← equation of line
Function or not a function?
If we want to check that a graph is function or not, we have a way to check by doing these steps.
Draw a vertical line, make sure that a line has to pass through or intercept a graph. See if a line intercepts a graph more than once.If a line intercepts a graph only one point, a graph is indeed a function. Otherwise, not a function but a relation instead. That includes if a line intercepts more than a point which doesn't make a graph a function.
From the graph, if we follow these steps, we will see that a line will only pass or intercept the graph only one point. Hence, the graph is indeed a function. The following graph that is shown is called "Parabola" for a < 0.
AnswerThe graph is a function.
f(-4); f(x) = x2 + x - 4
Answer: 8
Step-by-step explanation: In this problem,
we're asked to find f(-4) or the value of the function when x = -4.
To find the value of the function when x = -4,we simply plug in a -4 for
the x in our function and we have (-4)² + (-4) - 4 or 16 + -4 - 4 which is 8.
So f(-4) = 8.

A.y=62x
B.y=x+62
C.y=31x
D.y=x+31
Answer:
Step-by-step explanation:
if the bicyclist travels 62 miles in 2 h, he travels 62/2=31 miles per hour
y=nr miles
y=31x
choice C
Answer:
C
Step-by-step explanation:
Divide 62 by 2 to get the unit rate (31 miles per hour)
62/2= 31
X is used to show the number of hours. We are trying to determine the number of miles the biker will travel in x hours. So we would need to multiply 31 and "X" or we could write it as "31x"
